Abstract

An apparatus for generating a bandwidth extension signal comprises: an anti-sparseness processing unit which performs anti-sparseness processing on a spectrum of a low frequency band; and an FD high frequency extension decoding unit which performs extension decoding of a high frequency band in a frequency domain using the spectrum of the low frequency band, on which the anti-sparseness processing has been performed.
